In this section, you will go through the steps to run test case(s) provided by NCAR on AWS ParallelCluster.
Input data used for simulating the Weather Research and Forecasting (WRF) model are 12-km CONUS input. These are used to run the WRF executable (wrf.exe) to simulate atmospheric events that took place during the Pre-Thanksgiving Winter Storm of 2019. The model domain includes the entire Continental United States (CONUS), using 12-km grid spacing, which means that each grid point is 12x12 km. The full domain contains 425 x 300 grid points. After running the WRF model, post-processing will allow visualization of atmospheric variables available in the output (e.g., temperature, wind speed, pressure).
cd /shared
curl -O https://www2.mmm.ucar.edu/wrf/OnLineTutorial/wrf_cloud/wrf_simulation_CONUS12km.tar.gz
tar -xzf wrf_simulation_CONUS12km.tar.gz
Next we’ll prepare the data for a run by copying in the relevant files from our WRF install:
cd /shared/conus_12km/
WRF_ROOT=$(spack location -i wrf%intel)/test/em_real/
ln -s $WRF_ROOT* .
Please be aware there is a namelist.input in the current directory that you
do not want to overwrite. The link command will return the following
error, which is safe to ignore.
ln: failed to create symbolic link ‘./namelist.input’: File exists
